Chemical Name: Dioctyl sebacate

CAS No.: 122-62-3

DOS is an excellent cold-resistant plasticizer with good plasticizing effects and better heat, light and electrical properties. Compared to DBS, it offers similar plasticizing efficiency but has lower volatility and better water extraction resistance. It provides superior low-temperature flexibility and durability for products. DOS is primarily used in polyvinyl chloride (PVC), polystyrene, ethyl cellulose and synthetic rubber, and is especially suitable for producing cold-resistant cables and wires, artificial leather, films, sheets and other products. It is typically used in combination with phthalate esters to minimize migration.
